As title says, I feed my fishes right amount and mostly no left overs. But there is one thing I am really tired of and that is pellet mess. The left behind pellet residue from shrimp pellets. I need to get some kind of bottom feeder which can be safe with other aggressive fish. Please advise. I am inclined toward a catfish but no experience at all except when kept cories back in the guppies and mollies days
. I have pikes, JD and a Jaguar cichlid in there.
